Abiraterone (Zytiga) and Ketamine Therapy | Tovani Health

Zytiga (Abiraterone) (also: Yonsa)CYP17 inhibitor (metastatic prostate cancer)

Verdict at Tovani Health

Fully compatible with KAP.

Abiraterone and ketamine have no clinically significant interaction. Used for metastatic castration-resistant and castration-sensitive prostate cancer, always co-administered with prednisone (5-10mg) to prevent mineralocorticoid excess. The intrinsic considerations — hypokalemia, fluid retention, hypertension, hepatotoxicity monitoring, and the mandatory glucocorticoid co-administration — are abiraterone-class concerns independent of KAP.

If you take Zytiga regularly and are considering at-home ketamine therapy, the combination is generally safe at therapeutic doses. This page covers the brief pharmacologic context and what we do at intake.

How Zytiga interacts with ketamine

Abiraterone inhibits CYP17A1, blocking androgen synthesis in the testes, adrenals, and tumor tissue. It's a CYP2D6 inhibitor and CYP1A2 inducer, but neither pathway substantially affects ketamine (which is primarily CYP3A4/CYP2B6).

What we do at intake

Continue as prescribed including your prednisone. Disclose your current BP and electrolytes status.

Bottom line

Abiraterone and ketamine have no clinically significant interaction. Used for metastatic castration-resistant and castration-sensitive prostate cancer, always co-administered with prednisone (5-10mg) to prevent mineralocorticoid excess. The intrinsic considerations — hypokalemia, fluid retention, hypertension, hepatotoxicity monitoring, and the mandatory glucocorticoid co-administration — are abiraterone-class concerns independent of KAP.
